This invention, in part, an improvement on the Smoking pipe of myco-pending application, Serial No. 112,675, filed November 25, 1936, andis a continuation in part of that application, and in the illustrativeembodiment shown in Figs. 1 to 5 of the drawing, the present inventioncom- 6 prises a bowl 8 having a stem indicated, as a whole, by thenumeral 9 associated therewith, said stem being shown, in the presentinstance, as comprising a mouth piece II and a tubular portionindicated, as a whole, by the numeral I2 positioned intermediate thebowl 8 and the mouth piece II. The portion I2 is provided with a screwthreaded portion I3 adapted to be threaded into a portion of the bowl 8and comprises an enlarged portion I4 having ribs and grooves I5 and I6,respectively,formed therein in a manner to provide a relatively thinwall or shell of corrugated cross-section as clearly illustrated in Fig.3, and adjacent one of its ends the portion I2 is provided with anopening I1 having an internal diameter substantially equal to thesmallest diameter of the corrugated portion Il.

In the illustrative embodiment, a moisture retaining core or membershown, in the present instance, as a smoke filtering cartridge, formed25 preferably of fibrous material such, for example, as cotton or thelike, and indicated, as a whole, by the numeral I8is positioned in theportion I4 for ltering out solid substances such as particles oftobacco, tar and slugs entering the stem 9 from the bowl 8, and adaptedto absorb and retain any condensate from the bowl or other moisturewhich may enter the stem 9.

The cartridge I8 is provided on its exterior with a smooth outersurface, indicated at I9 35 (Fig, 3), produced by treatment of thefibrous material in a manner to retain the cartridge in proper form andyet permit the passage of air and smoke therethrough.

It will be observed that the diameter of the cartridge I8 issubstantially equal to that of the smallest internal diameter of thecylindrical corrug'ated portion I4 of the stem and that the-surface ofthe cartridge cooperates with the corru` gations of the portion I4 in amanner to provide a plurality of elongated, substantially parallel,annularly spaced smoke passages or ducts 2| communicating with the bowl8 through spaces between radially extending ribs 22 provided for spacingthe end of the moisture retaining cartridge from the end of thechambered portion Il of the stem, and through the passages 2|, the smokemay pass freely to the mouth piece Il of the pipe.

It will be observed also that by reason of the relatively thin characterof the material constituting the corrugated wail of the portion I4 ofthe stem, and the substantial surface area obtained by reason of thecorrugations, that in the passage of smoke through the ducts 2I aconsiderable amount of heat from the smoke will be thrown off ordissipated through the wall of the portionv I4, thereby cooling thesmoke to some extent before passing to the mouth piece Il.

For further cooling the smoke before passing to the mouth piece II, thechambered portion I4 is provided, preferably, adjacent its end nearestthe mouth piece 'I and, preferably, in one of the grooves I6 between apair of the ribs i5 as illustrated in Fig. 3, with an air intake openingor port 23 adapted to communicate-With the ducts 2| for admitting airthereto.

For automatically controlling the admission of air through the port 23,a valve head 24 is shown, in the present instance, as operativelyrelated to the port 23 in a manner to normally close the port, the valvehead 24 being mounted adjacent vone end of a thermostat 25 shown, in thepresent instance, as of the well known laminated bimetal type,consisting of layers of dierent metals having relatively differentcoeiiiciencies of expansion, and secured adjacent their opposite ends bymeans of rivets 23 or the like to the wall of the portion Id.

By such an arrangement, it will be apparent that when the heat of thesmoke transmitted through the wall or shell of the chambered portion I4is suiiicient to actuate the thermostat 25, the valve head 24 will bemoved from operative relation or closed position with respect to theport 23 as illustrated in Fig. 4, in proportion to the effect of theheat on the thermostat and in a'manner to permit air to enter the port23 and mix with the smoke passing to the mouth piece I I, thereby addinga cooling medium to the smoke before entering the mouth of the user.

It will be noted that by reason of the location of the thermostat 25andthe sensitiveness of its construction, the port 23, if desired, maybe readily and conveniently maintained in closed position,notwithstanding the Aaction of the thermostat, merely by exerting alight manual pressure on the free end portion of the thermostat.

ually as well as automatically controlled.

For :facilitating the removal of the cartridge vI8 from the chamberedportion I4 when-it is desired to replace the cartridge, a yoke 28 (Figs.

2, 3 and 5) is adapted to surround the cartridgelengthwise thereof, andis'providedwith a handle vmember or rod 29 adapted to extend beyond theopen end of the chambered portion I4 in a manner to be grasped by thefingers when the mouth piece I I isremoved, for withdrawing the yoke andcartridge from the chamber, after which a fresh' 2Ia and at itsoppositevend with an air intake opening or port 32 adapted tobe'controlled by a.

valve head 24a mounted on the free end of an annular ring-like bi-metalthermostat 25a positioned in an annular groove ,34 formed in the bowl 8aand'secured thereto at its opposite end by means of rivets or securingpins 23a.

The function of the thermostat 26a is substantially like that describedwith reference to the thermostat 25 of Figs. 2, 3 and 4 in that 'uponheating of the thermostat by reason of the heat within the bowl 8a, thevalve head 24a will be moved out of cooperative relationship withrespect. to the port 32 in proportion to the action of the heat on thethermostat, and in a manner. to admit air through the port 32, by-passland into the smoke duct 2Ia for cooling the smoke before passing to andthrough the mouth piece of the pipe. v

It will be observed from the foregoing description that the presentinvention provides a novel construction and arrangement whereby air maybe admitted to the-smoke ducts or passages for cooling the smoke beforereaching the mouth of the user, and wherein the admission of air isautomatically controlled by thermostatically operated means which, ifdesired, may also be under the control of the user.

Obviously, the present invention is not limited to the preciseconstruction and arrangement shown and described as the same may bevariously modified. Moreover, all the features of the invention need notbe used conjointly as the same may be used to advantage in variouslydifferent combinations and subcombinations.
